A cross-sectional analytic study was conducted.
To collect normative data on back extensor endurance holding times and evaluate the discriminative validity of the Biering-Sorensen test in a group of coal miners in Australia.
Low back pain is a common complaint among those working in the Australian coal mining industry. One test that may be predictive of first-time episodes of low back pain is the Biering-Sorensen test of back extensor endurance strength. While this test has been evaluated in overseas sedentary populations, normative data and the discriminative ability of the test have not been evaluated with coal miners.
Eighty-eight coal miners completed a questionnaire for known risk factors for low back pain, performed the Biering-Sorensen test, and undertook a test of aerobic fitness. Data analysis was performed to describe the groups and to determine whether any significant difference existed between those with a past history of low back pain and those without.
Significantly lower than expected holding times were found in this group of coal miners (mean 113 s). This result was significantly lower than demonstrated in previous studies (mean 138 s, t87 = 6.32, p < 0.001). When holding times for those with a past history of low back pain were compared with times for those with no history of low back pain, the difference was not statistically significant (t86 = 1.56, p = 0.12), nor was there a significant difference in fitness between those with a past history of low back pain and those without (t86 = 0.47, p = 0.64).
DISCUSSION/CONCLUSIONS: Coal miners in Australia have lower than normal Biering-Sorensen holding times. This lower back holding time does not differ between coal miners with a past history of low back pain and those without.
进行了一项横断面分析研究。
收集背部伸肌耐力保持时间的标准数据，并评估比林 - 索伦森测试在澳大利亚一组煤矿工人中的判别效度。
腰痛是澳大利亚煤矿行业从业者的常见问题。一种可能预测首次腰痛发作的测试是背部伸肌耐力强度的比林 - 索伦森测试。虽然该测试已在海外久坐人群中进行评估，但尚未对煤矿工人的标准数据和该测试的判别能力进行评估。
88名煤矿工人完成了一份关于腰痛已知风险因素的问卷，进行了比林 - 索伦森测试，并进行了有氧适能测试。进行数据分析以描述各组情况，并确定有腰痛病史者和无腰痛病史者之间是否存在显著差异。
该组煤矿工人的保持时间显著低于预期（平均113秒）。这一结果显著低于先前研究中的结果（平均138秒，t87 = 6.32，p < 0.001）。将有腰痛病史者的保持时间与无腰痛病史者的保持时间进行比较时，差异无统计学意义（t86 = 1.56，p = 0.12），有腰痛病史者和无腰痛病史者在适能方面也无显著差异（t86 = 0.47，p = 0.64）。
讨论/结论：澳大利亚煤矿工人的比林 - 索伦森保持时间低于正常水平。有腰痛病史的煤矿工人和无腰痛病史的煤矿工人之间的背部保持时间没有差异。
